Guatemala Fakes and Forgeries

Collecting the stamps of Guatemala is an interesting and potentially complex challenge, and collectors of the country are helped by a large body of available information. El Quetzal editor and former International Society of Guatemala Collectors (ISGC) president David Reitsema has added to this information by writing these articles to assist ISGC members and other ISGC website visitors distinguish between genuine stamps and fakes.

More articles in this series about Guatemala Fakes and Forgeries will continue to be posted periodically on the website.
